Unable to recognize workspaceid in Ant4Eclipse

Question

Here is my buildfile:

<project name="ant-in-eclipse" basedir="."
         xmlns:ant4eclipse="antlib:org.ant4eclipse"
         xmlns:antcontrib="antlib:net.sf.antcontrib" default="compileAndJar" >

  <taskdef uri="antlib:net.sf.antcontrib"
           resource="net/sf/antcontrib/antlib.xml" />

  <!-- define ant4eclipse tasks -->
  <taskdef uri="antlib:org.ant4eclipse"
           resource="org/ant4eclipse/ant/antlib.xml" />

  <import file="/data/temp/ANT/ANT4/macros/a4e-jdt-macros.xml"/>
  <target name="compileAndJar">
      <macrodef name="build">
          <attribute name="workspaceDirectory" default="deploy" />
          <sequential>
              <echo>Hi</echo>
          </sequential>
      </macrodef>

      <buildJdtProject workspaceDirectory="${workspaceDirectory}"
                       projectname="wfn-common.jar">
      <finish>
          <jar destfile="deploy/wfn-common.jar">
              <ant4eclipse:jdtProjectFileSet destination="."
               projectname="${buildJdtProject.project.name}" />
          </jar>
      </finish>
      </buildJdtProject>
   </target>
</project>

I am getting this error

/data/temp/ANT/PTO_Build/WFN_Framework/wfn-common/sample.xml:21: The following error occurred while executing this line:

Can anyone please help me out?

Answer 1

The error is in the file you import:

< import file="/data/temp/ANT/ANT4/macros/a4e-jdt-macros.xml"/>

I guess your buildJDTProject target is defined there and there is an error in how it is defined.

• Take a look at that file /data/temp/ANT/ANT4/macros/a4e-jdt-macros.xml
• Look at line 105, which is where your build fails

I'm guessing it will be at a buildJDTProject target. I'm guessing that target contains workspaceid attribute, which appears to be illegal.

You could remove the attribute, or figure out why it was included in first place. Maybe it works with different version of your ant jdt library?

Two further guesses (I'm not familiar with ant4eclipse BTW). Regarding the buildJdtProject task of ant4eclipse...

The document says

Either 'workspaceDirectory' or 'workspaceId' has to be specified

You are passing workspaceDirectory in the target in your build script. Maybe workspaceId is specified by default in the macro in that imported file. If so, maybe you end up with both workspaceDirectory AND workspaceId defined and that is illegal. However, that idea doesn't match the error message you're getting.

Alternatively, maybe ant4eclipse is case-sensitive about attribute names. That would be unusual for Ant, it is generally case-insensitive. But the ant4eclipse doc gives the attribute name as workspaceId and your error message says workspaceid is not supported. So maybe try changing the case in that imported file.
